Saffron and its effects on the nervous system

What it found

Saffron and its active compounds showed brain-protecting, anxiety-reducing, and memory-improving effects in lab and human studies.

Some of these compounds can cross into the brain.

What they found

Studies in people and animals

Reaching the brain

Some active parts of saffron are easily absorbed by the body. They can also pass through the blood-brain barrier to reach the brain.

Brain and mood effects

Lab and human studies found that saffron and its compounds, such as safranal, crocin, and picrocrocin, protect the brain. They also reduced anxiety, lifted mood, and improved learning and memory.

Other findings

Active plant chemicals

Saffron contains several active compounds including apocarotenoids, monoterpenoids, flavonoids, phenolic acids, and phytosterols. These have been studied widely in both lab and human research.

What the authors conclude

  • They suggest saffron and its active compounds could be useful ingredients for making medicines that target nervous system disorders.

How it was done

Saffron has long been used as a medicine in Chinese, Ayurvedic, Persian, and Unani traditions. Scientists wanted to gather what is known about its active parts and how they affect the brain.

The authors gathered and examined existing lab and human studies on saffron. They looked at its plant chemicals, how well the body absorbs them, and their effects on nervous system conditions. The abstract does not state how many studies were included or how long they lasted.

What it can’t tell you

  • We summarised it from the abstract only.
  • This work gathers past studies rather than testing saffron directly, so it cannot prove cause and effect on its own.
  • Lab results in animals or cells do not always match what happens when people eat saffron.
